Perhaps the 1110st striking differences dre in the range of the tide. This varies so trelllendously that what the inhabit- an ts of one place Inigh t consider dis- astrousl) high water would be regarded as no tide at all by coastal COlll111unities only a hundred 11liles distant. The high- est tides in the wOlld occur in the Bay of Fund); there is a rise of about fifty feet dUrIng the spring tIdes in Vlinas Basin, near the head of the bay.. i\.t least five other places have a tidal range of 11lore than thirty feet: Puerto Gallegos, in .L-1.rgentina; Cook Inlet, in ...-\laska; Frobisher Bay, in Davis Strait; the Koksoak River, e111ptying into U n- gava Bay; and the Gulf of St.-Ma]o, in France. In lllany other places, "high tide" 111 a), 11lean a rise of only a foot or "0, or only a few inches. The tides of Tahiti rise and fall in a gentle 11love- 111ent, and there is a difference of no more than a foot between high and low ,-. water. Indeed, on 11loSt oceanic islands, the range of the tide is slight. But it is not safe to generalize about the kinds of places that have high or low tides. i\.t the .L tlantic end of the Panallla Canal, the tidal range is one or two feet, but at the Pacific end, oniy forty miles away, the range is frolll twelve to SIxteen feet. \Vhat is it about one place that will brIng forty or fifty feet of water rising about its shores, while another place, lying under the sallle moon and sun, has a tide of only a few inches? \Vhat can be the explanation, for exalllple, of the great tides in the Bay of Fundy, when only a few hundred 11liles away, at Nantucket Island, the tide range is little more than a foot The 11lodern theory of tidal oscillation seelllS to offer the best explanatIon of such local differ- ences-the rocking motion of water in each natural basin about a central, vir- tually tideless node.. Places near the node of such a basin have a slllall range of tide; those near the ends of the basin Inay have a large rise and fall of water. The Bav of Fund) tides are particularly large because the oscillation in this basin has a twelve-hour period, coincid- ing wIth that of the ocean tide. i\.lso, the narrowing and shallowing of the upper bay pile up huge 11lasses of water th e re The tidal rhythlll, as well as the tidal range, varies from ocean to ocean. To those who live along either the eastern or the western shores of the Atlantic Ocean, the rhythm of two high tides and two low tides every day seelllS nor- mal.
